Amalensi e-Telecentric, eyaziwa nangokuthi amalensi e-tilt-shift noma amalensi e-soft-focus, anesici esibaluleke kakhulu sokuthi isimo sangaphakathi selensi singaphambuka enkabeni yekhamera.
Uma ilensi evamile idubula into, ilensi kanye nefilimu noma inzwa kusendaweni efanayo, kuyilapho ilensi ye-telecentric ingajikeleza noma ithambekise isakhiwo selensi ukuze isikhungo se-optical selensi siphambuke enkabeni yesenzwa noma ifilimu.
1,Izinzuzo kanye nokungalungi kwamalensi e-telecentric
Inzuzo 1: Ukujula kokulawula insimu
Amalensi e-Telecentric angagxila ngokukhetha ezingxenyeni ezithile zesithombe ngokushintsha i-engeli yokuthambekela kwelensi, ngaleyo ndlela evumela abathwebuli bezithombe ukudala imiphumela ekhethekile yokugxila ekhethiwe, njengomphumela we-Lilliputian.
Inzuzo 2: Umbonocukulawula
Enye yezinzuzo eziyinhloko zamalensi e-telecentric kubathwebuli bezithombe bezakhiwo ukuthi anikeza ukulawula okukhulu kokubona. Amalensi avamile angabangela imigqa eqondile ezithombeni (njengephansi elihlanganisiwe lesakhiwo) ukuthi ibonakale igobile, kodwa amalensi e-telecentric angashintsha umugqa obonakalayo ukuze imigqa ibonakale iqondile noma ijwayelekile.
Inzuzo 3: I-engeli yokubuka yamahhala
Amalensi e-Telecentric ayakwazi ukudala ama-engeli ahlukene okubuka akhululekile (okungukuthi ukubuka okungahambisani nenzwa). Ngamanye amazwi, ukusebenzisa i-ilensi ye-telecentricikuvumela ukuthi uthwebule insimu ebanzi yombono ngaphandle kokuhambisa ikhamera, okuwusizo kakhulu kubathwebuli bezithombe bezakhiwo kanye nezindawo.
Ilensi ye-telecentric
Ububi 1: Ukusebenza okuyinkimbinkimbi
Ukusebenzisa nokuqonda amalensi e-telecentric kudinga amakhono akhethekile kanye nokuqonda okujulile kwezithombe, okungaba nzima kwabanye abathwebuli bezithombe abasaqalayo.
Ububi 2: Kubiza kakhulu
Amalensi e-telecentric abiza kakhulu kunamalensi avamile, okungaba yintengo abanye abathwebuli bezithombe abangeke bayamukele.
Ububi 3: Izicelo zilinganiselwe
Nakubaamalensi e-telecentricziwusizo kakhulu ezimweni ezithile, njengezithombe zezakhiwo kanye nezithombe zezwe, ukusetshenziswa kwazo kungase kulinganiselwe kwezinye izimo, njengezithombe zezithombe, izithombe zesenzo, njll.
2,Umehluko phakathi kwamalensi e-telecentric namalensi ajwayelekile
Umehluko omkhulu phakathi kwamalensi e-telecentric namalensi ajwayelekile ulele kulezi zici ezilandelayo:
Ukujula kokulawula insimu
Kulensi evamile, i-focal plane ihlala ihambisana ne-sensor. Kulensi ye-telecentric, ungatshekisa ilensi ukuze ushintshe le plane, ukuze ukwazi ukulawula ukuthi iyiphi ingxenye yesithombe ebukhali nokuthi iyiphi ingxenye yesithombe efiphele, okukunikeza ukulawula okukhulu phezu kokujula kwensimu.
Izinhlelo zokusebenza zezithombe ze-telecentric lens
Ukuhamba kwelensi
Ku-lens evamile, ilensi kanye nenzwa yesithombe (njengefilimu yekhamera noma inzwa yedijithali) zihlala zihambisana. Ku-lens ye-telecentric, izingxenye zelensi zingahamba ngokuzimela ngaphandle kwekhamera, okuvumela umugqa wokubona welensi ukuthi uphambuke endizeni yenzwa.
Le mvelo ehambayo yenzaamalensi e-telecentrickuhle kakhulu ekuthwebuleni izithombe zezakhiwo kanye nezindawo, njengoba kushintsha umbono futhi kwenza imigqa ibonakale iqondile.
Intengo
Amalensi e-telecentric ngokuvamile abiza kakhulu kunamalensi avamile ngenxa yokwakheka kwawo kanye nokusetshenziswa kwawo.
Aukunyakaza
Amalensi e-telecentric ngokuvamile adinga ukuhlonyiswa ngembobo enkulu, ewusizo ekuthwebuleni ezindaweni ezinokukhanya okuphansi.
Kufanele kuqashelwe ukuthi nakubaamalensi e-telecentricingadala imiphumela ebonakalayo ehlukile, iyinkimbinkimbi kakhulu ukuyisebenzisa kunelensi evamile futhi idinga amakhono aphezulu kumsebenzisi.
Imicabango Yokugcina：
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
